The cost of synthetic blend oil lies in the middle between conventional oil and full-synthetic. But, its qualities are dwarfed when compared to full-synthetic oils. Overall, synthetic blend oil performs better than conventional oil and lasts longer. Synthetic blend oil offers the best of both worlds as they are made using natural and synthetic materials. Typically, the price difference is around $20 to $40.

However, full synthetic oil is more expensive than conventional oil as well. Additionally, these oils have a longer lifespan, meaning that you can travel longer before needing an oil change. These oils are more refined than conventional oil and offer better protection than them. To put it another way, this 2nd number refers to the viscosity of the oil as it operates when the engine is warmed up to operating temperature. The number that comes after the dash indicates the high-temperature viscosity of the particular motor oil. At lower temperatures, thinner oil flows faster through the engine and lubricates the components more quickly. A lower number indicates oil that is thinner in viscosity. The first one, located to the left of the W indicates the low-temperature oil viscosity level. Oil Number Meaning #2 – The 1st NumberĮvery motor oil label comes with two different numbers. Unsurprisingly, the letter “W” stands for Winter. Here, the low-temperature viscosity is aimed at simulating starting up the vehicle during a cold winter. The viscosity of motor oil is measured at both cold and high temperatures. However, with modern technological advancements, using the same grade oil throughout the year has become a possibility. They had to do this because the properties of motor oil changed with temperature. In the old days, owners had to use oil with one viscosity level during the summer and a different grade during the winter. Oil Viscosity ChartĪn oil viscosity chart has a letter and some numbers that indicate the resistance of oil flow at different temperatures. In the next sections, we will tell you about oil viscosity in more detail. The term viscosity was mentioned several times so far. It oversees over 1600 practices and standards and serves several industries including the likes of aerospace, trucking, and petroleum. Currently, the main role of the SAE is to ensure the consistency of products across the global markets. He, along with Andrew Ricker founded the SAE as an organization for the vast number of automotive engineers working across America.īy 1916, the SAE had evolved into an organization that set industrial standards. In fact, one of its original founders was none other than Henry Ford. The Society of Automotive Engineers has a history that expands over a century. As a result, the letters “SAE” refer to the oil viscosity specification of particular motor oils. SAE stands for the “Society of Automotive Engineers”, which are the group that designed the viscosity coding system used in motor oils. They have a specific meaning that every automotive enthusiast should know about. However, these are not some random, symbols. These three letters can be seen on many motor oil containers. If you are keen on learning about oil number meaning, you definitely would have come across the letters “SAE”. First, we will tell you all about what the letters “SAE” on oil labels mean. So, let’s get along with our discussion without waiting any longer. Whether you change the engine oil at home or get it done by a mechanic, knowing the meaning of oil numbers can come in handy on many occasions. Putting the incorrect type of oil into the engine can reduce efficiency, worsen performance and even damage internal engine components.

Knowing how to select the correct oil for your vehicle is really important. In this article, we will tell you everything there is to know about the oil number meaning. Well, if that’s the case for you, don’t worry. These labels include many numbers and letters, but I’m pretty sure that most don’t properly really understand their meanings. If you own a vehicle, you most probably have seen the labels on motor oil canisters.
